Question

Write a short note on Heisenberg's Uncertainty principle.

Answer 1

Heisenberg's Uncertainty principle:

This principle was given by Werner Heisenberg in $1927$. It states that it's not possible to measure simultaneously both the position and momentum of microscopic particle.

Mathematically it is given as:
$\Delta x\times \Delta p\ge \frac{h}{4\pi }$

or $\Delta x\times \Delta \left(m{v}_x\right)\ge \frac{h}{4\pi }$

or $\Delta x\times \Delta v_x\ge \frac{h}{4\pi m}$
